Hillary Clinton is vowing to take on the entire Republican field, especially GOP front-runner Donald Trump, on the burning issue of immigration reform.

Working the campaign trail over the Labor Day weekend, Clinton added she plans to commence pressing Trump and others for specific details on immigration proposals, which they have loudly yet vaguely touched upon.

"The other side has said they will spend, do and say anything to win back the White House," Clinton told a crowd in Iowa. She later added, "I am absolutely confident that whatever they throw at me, I can throw it right back."

Clinton also pledged to raise incomes, expand early childhood education and defend the Affordable Care Act. Even more demonstratively, she spoke about immigration reform and called into question some of the proposals thus far laid out by Trump.

"I'm going to be pressing very hard to get specifics, because there aren't any specifics," she said. "This is just the kind of political rhetoric that doesn't belong in our election."

In recent days, Clinton has also forcefully criticized her republican rivals over some of their stances on women's rights issues.

On Saturday, she chided Trump over his claims that he "cherishes" women, despite engaging in an ongoing feud with Fox News anchor Megyn Kelly, for which he has been accused of blatant misogyny.

"Well, if it's all the same to you Mr. Trump, I'd rather you stop 'cherishing women' and start respecting women," she said.

The former secretary of state also spent part of her weekend firing back at former republican Vice President Dick Cheney over recent criticisms he lodged against the Obama administration over the nuclear arms deal it made with Iran.

"Iran was on a pretty fast track toward a nuclear weapon when Barack Obama became president," she said.

Clinton's clearly aggressive return to Iowa comes amid a new NBC poll showing her losing ground to Democratic rival Bernie Sanders in that state and in New Hampshire.
